Aregular skate park is 60 yards long and 50 yards wide. plans call for increasing both the length and the width of the park by x yards. write a function l(x) that gives the new length of the skate park in terms of x. write a function w(x) that gives the new width of the park in terms of x. what does (l*w)(x) represent in this situation? write and simplify the equation for (l*w)(x). find (l*w)(x)
